Embedded Memories
Internal High-Speed Flash
– 256KBytes (AT32UC3A3256/S)
– 128Kbytes (AT32UC3A3128/S)
– 64Kbytes (AT32UC3A364/S)
0 wait state access at up to 42MHz in worst case conditions
1 wait state access at up to 84MHz in worst case conditions
Pipelined Flash architecture, allowing burst reads from sequential Flash locations, hiding
penalty of 1 wait state access
Pipelined Flash architecture typically reduces the cycle penalty of 1 wait state operation
to only 15% compared to 0 wait state operation
100 000 write cycles, 15-year data retention capability
Sector lock capabilities, Bootloader protection, Security Bit
32 Fuses, Erased During Chip Erase
User page for data to be preserved during Chip Erase
Internal High-Speed SRAM
– 64KBytes, Single-cycle access at full speed on CPU Local Bus and accessible through the
High Speed Bud (HSB) matrix
– 2x32KBytes, accessible independently through the High Speed Bud (HSB) matrix

Physical Memory Map
The System Bus is implemented as a bus matrix. All system bus addresses are fixed, and they
are never remapped in any way, not even in boot.
Note that AVR32 UC CPU uses unsegmented translation, as described in the AVR32UC Techni-
cal Architecture Manual.
The 32-bit physical address space is mapped as follows:
